The present invention relates to an internal combustion engine cont starter control coordina engine fuel valve. It is type referred t ber is employed to rend rol comprising an engine ted with a control for the among the objects of the ovide a coordinated control of the o in which a single operating memer the starting motor operative to crank the engine and to place the fuel valve in the most advantageous position for startmg the engine, said control being so constructed ed that, when the control member is stop the operation'of thestarting motor, the fuel valve will automatically be moved to a position the engine most advantageous for the running of during the Warming up period. In this connection it is a further object to provide for controlling the fuel valve independently of the engine starter control.

Further objects invention will be appare scription, referenc ing drawing, wherein a and advantages of the present nt from the following dee being had to the accompanypreferred embodiment of one form of the present invention is clearly shown.

In the drawing: The figure of the illustrating the use of t is in part the longitudi drawing is a wiring diagram he present invention and nal sectional view of the controller embodying the invention.

Referring to the drawing, a generator nected to a storage battery relay 22 and a wire 23. the engine is connected it is con- 2! through a cut-out The starting motor 24 for with the storage battery through a wire 23 and an electro-magnetic switch 25 having a magnet 0 oil 26 which is connected to the wire 23 by an ignition switch 27 and by a second switch included will now be described.

The controller compr sleeve 3i, the threaded through an instrument nut 33 for securing the in the controller which isesa frame 3t having a portion of which extends board 32 and receives a frame to the board. The

frame (it insulatingly supports stationary contacts 34 and 35 connected, respectively, by wires 35 and 3'! with the ma switch 27.

The contacts 34 and 35 able by a movable contact 38 insulatingly carried gnet coil 25 and ignition are engageby a sleeve 39 which extends through the sleeve 3! and is secured to a handle or knob 46. The

sleeve 39 is slidable upon a tube M integral with a bracket 42 secured by screws 43 to the bracket 30. The tube 4! supports a slidable rod 44 attached to a Bowden wire 45 slidable within a Bowden wire tube 46 attached to the tube 4 I. The

wire 45 is connected wit ha lever 41 for operating Flint, Mich, mesne assignments, to General assignor, by Motors Corch., a corporation of 1933, Serial No. 685,519 (Cl. 123-479) To start the engine, the operator first closes the ignition switch 27 and then pulls the knob 30 toward the right thereby causing the movable contact 38 to move into engagement with the stationary contacts 34 and 35 against the action of a spring 52. The circuit of the coil 25' being completed, the electi e-magnetic switch operated by said coil is closed in order to connect the starting motor 2 with the battery. -The movement of the knob '36 to close the switch 35, 38, 3t, will cause the knob 58 to move in the same direction thereby causing the valve 48 to move into open position indicated at @812 which position has been predetermined to be the most advantageous for starting the engine. As soon as the engine becomes self-operative theoperator will release the knob 39 thereby permitting the spring 52 to separate the contact 38 from the contacts 3t and 35 and to return the knob lll to normal position against the end of the sleeve M. The circuit of the coil being broken, 32 will open the circuit of the starting motor Ell.

The spring 52 however, does not effect the return of the knob 55 to normal position. The return of the knob it to normal position permits the spring as to move the wire 35 toward the left in the drawing in order to move the valve 43 toward closed position. The valve 43, however, does not move entirely to the normal position but stops automatically at some position as at 480 which has been selected as being the most adthe electro-magnetic switch engine. The valve dtc is caused to stop at this position due to the fact that, as the rod 44 moves from its extreme right hand toward its extreme left hand position its motion will be arrested when a groove 55 provided by the rod it passes into alignment with two spring urged balls 56 carried by a bracket 52. When these balls 55 are moved into the groove '55, the resistance offered thereby is sufiicient to overcome the spring 39. its normal position 43a but stops at its intermediate position 4.80. After the engine has been operating for time sufiicient to insure its further operation at idling speed, the knob 50 is pushed toward the knob ii] by the operator so that the valve 88 may be returned to position for engine idling.

It will be noted that in the drawing the man- Hence, the valve 48 is not returned to" trol member may be operated independently of i source with said engines comprising a trol valve for regulating engines comprising a source adapted tion of the button ill is arranged to close the circuit through an electromagnetic switch 25 which is the main starting motor switch. However, it will be understood that if so desired, the manually operated switch could be the main starting motor switch itself and the magnetic switch could be eliminated. All that it would be necessary to do to accomplish this purpose would be to connect the wire 3? to the wire 23 leading to the battery and connect the wire 36 leading from the contact 3% directly to the starting motor instead of to the winding of the magnetic switch 25. The form shown in the ferred form of the invention, but the other construction above referred to could be utilized just as well if it were not desired to use the magnetic switch to control the starting motor circuit.
